Title: Bucket inverter for reclaimer of bucket wheel type
Inventor: NONOMURA ZENZOU
IPC: B65G65/20
Filed: 1982-04-30
Abstract: PURPOSE:To heighten the safety of inversion work and prevent a wheel from being shocked at the inversion of the bucket of a reclaimer, by providing an operating rod and a lever for securing the bucket, on the wheel to all mechanically perform the inversion work. CONSTITUTION:To invert a bucket 3a, the guide member of a guide unit 11 is moved down and a wheel 1 is turned clockwise. When the guide member 14 has pushed an operating rod 5 against a spring 6, an engaging member 8 is moved to a recess 10. At the same time, the brim 9a of the bucket 3a is disengaged from the member 8. With the turning of the wheel 1, the bucket 3a turns over due to its weight and the opposite brim part is put on a following engaging member 8. As the bucket 3a approaches a guide unit 12, a following operating rod 5 is pushed by the guide member of the guide unit against the spring 6 so that the following engaging member 8 is fitted into the recess 10. The operating rod 5 is then returned to the original position by the spring 6. As a result, the bucket 3a is secured in an inverted state.

Title: Optical device with stop device
Inventor: INABA HIROYOSHI
IPC: G03B11/00
Filed: 1990-03-24
Abstract: PURPOSE:To project unnecessary reflected light from an image pickup surface to outside its optical path when it is reflected by the surface of a stop member and to prevent a ghost, a flare, etc., from being generated by arranging the stop member which constitutes part of a stop device so that its surface slant to a surface perpendicular to the optical axis of its optical system by a specific quantity. CONSTITUTION:A stop blade 3 as the stop member which constitutes part of the stop device 10 is mounted so that the stop blade surface 3a slants toward a subject by an angle alpha deg. to the surface perpendicular to the optical axis L. An ND filter as an optical attenuation part which provides operation for attenuating the quantity of incident light is mounted on part of the stop blade surface 3a to attenuates light made incident on the image pickup surface 4a of an image pickup element. Then the ND filter reflects the unnecessary reflected light which is reflected by the image pickup surface 4a to outside the optical path to remove the generation of the harmful ghost, flare, etc., which are made incident again on the image pickup surface 4a. Consequently, the assembly machining is facilitated, the need for the crape processing of the stop blade itself is eliminated, and picture quality is prevented from deteriorating owing to the ghost, diffraction, etc.

Title: Fabrication of semiconductor device
IPC: H01L21/768
Filed: 1992-03-31
Abstract: PURPOSE:To bore a through hole as designed by growing an interlayer insulation film and a low reflectance conductive film on a semiconductor chip on which a first aluminum wiring is formed and then making a through hole by means of etching. CONSTITUTION:After forming first aluminum wirings 8a, 8b on a semiconductor chip, a silicon oxide film 9 is grown on the entire surface through plasma CVD and then a titanium nitride film 14 is grown through sputtering. A photoresist film is then applied on the entire surface and subjected to exposure through a photomask. Since the incident light to the photoresist film is scarcely reflected on the Ti-N film, a photomask pattern as designed is formed on the photoresist film after development. The Ti-N film 14 and the silicon oxide film 9 are then etched to make through holes 12a, 12b through the first aluminum wirings 8a, 8b. According to the method, through holes can be bored as designed.

IPC: B60R1/06
Filed: 1992-02-26
Abstract: PURPOSE:To provide a motor driven mirror which can enhance waterproof by reducing the number of parts and also can leave its housing less damaged when its mirror housing is subjected to outside force. CONSTITUTION:A first motor 13 and a second motor 14 are housed in a motor housing body 12 interposed between a mirror housing 11 on which a mirror 9 is mounted, and a base section 2. With the two motors operated, the mirror angle of the mirror can be regulated and the mirror housing 11 can be housed in the side of a car body. The device can be made more inexpensive, lighter in weight, and more compact. Even when the mirror housing 11 is subjected to a great outside force, damage can be checked not to be extended beyond the mirror housing 11 and the mirror 9, so that the damage can be minimized. Since the mirror 9 is mounted on the mirror housing 11, there is no need for a gap between the mirror 9 and the mirror housing 11, and its inside will never be damaged by rain coming in, so that waterproof is markedly enhanced.

Title: Heat insulating panel with groove and its manufacture
Inventor: NABEYA HIDEO
IPC: E04B1/80
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent the accumulation of moisture and the occurrence of dew condensation on the surface of a heat insulating material after the work by making a groove extending in the length direction of a heat insulating panel on one surface of the insulating panel consisting of a surface member laminated on a foamed resin insulation material and its surface. SOLUTION: Depth of a groove 3 is 3 to 15 mm, a proportion of the width of the groove 3 occupying in the width direction of heat insulating panel is about 30% to 80% and the groove 3 is installed in a width direction in such a manner that the grooved insulation panel can be divided into two with 1/2 width. Next, the surface member 2, 2' can be easily formed by pressuring and compressing from the above. In this pressuring and compressing method, the heat insulating panel made by laminating the surface member 2, 2' made continuously is formed to a groove 3 continuously by pressuring by a roll on the line. Then, the panel is formed by only a synthetic resin famed body 1 and the surface member 2, 2' thereby making the cutting easier, and the processing is performed freely in response to the fluctuation and error of the dimensions of the location of work.  By doing this, the grooved insulation panel can be used as insulation for a wall, roof, floor or others and an air passage for air circulation can be provided.

Filed: 1994-04-14
Abstract: PURPOSE:To make highly precise and quantitative control possible with an electromagnetic or an eddy current type film thickness measuring instrument employed even though a paint film layer is formed over the surface of a ground made of nonmetallic materials. CONSTITUTION:A metallic sheet 8 is laid over the surface of a ground made of nonmetallic materials such as concrete wall 2a, and a paint film layer 4 is formed over the metallic sheet 8. As the metallic sheet 8 develops electric correlation corresponding to intensities of magnetic force and electric field through the paint film layer 4 even if the surface of the ground is made of nonmetallic materials, film thickness of the paint film layer 4 can be measured, using such electric correlation, with an electromagnetic or an eddy current type film thickness measuring instrument 10, and thereby highly precise and quantitative control of the film thickness can be available.

Title: Production of heat-insulating composite pipe by two-stage casting
Inventor: KAWAI TOORU
IPC: C23C4/18
Filed: 1984-04-16
Abstract: PURPOSE:To improve mechanical strength and operability by casting a molten metal for forming an outside layer into a centrifugal casting mold through one aperture thereof as the 1st stage and casting a molten metal for forming an inside layer into said mold through the other aperture as the 2nd stage. CONSTITUTION:A cylindrical core material P consisting of heat insulating fibers P3 are disposed between an outside core pipe P1 and a circular core pipe P2 having plural gas vent holes. These pipes and core material are grapsed by means of a 1st stage side ring and a 2nd stage side ring 42 and are fixed to the casting mold 1. The molten metal M1 for the outside layer is cast from a 1st stage side hopper 31 into a molten metal pool A1 while the mold 1 is rotated. The molten metal M1 is filled in a space C by which the outside layer is formed. The molten metal M2 for the inside layer is then cast therein from a second stage side hopper 32 and is filled in a space B, by which the inside layer is formed. Mixing of the molten metals M2 and M1 for the inside and outside layers is obviated and the change in the volume of the alloy components in the inside layer of the composite pipe is prevented by the above-mentioned method. Since the inside layer is cast before the formation of solid solution of the outside layer, the mechanical strength and operability are improved.
